Underdocumentation of laboratory-defined acute kidney injury in internal medicine wards: a retrospective cohort study.
Article in Renal failure, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Acute kidney injury (AKI) is common among hospitalized patients, but laboratory-defined AKI may not be documented. We aimed to determine the frequency of undocumented AKI in internal medicine wards, compare clinical characteristics and in-hospital outcomes by documentation status, and explore associated factors. We conducted a retrospective single-center study of adult hospitalizations with AKI defined by serum creatinine criteria; urine-output criteria were unavailable. Because reliable pre-admission creatinine values were not consistently available, the lower of admission and discharge creatinine was used as reference and compared with maximal creatinine. Among 161 hospitalizations in 161 unique patients, 39 (24.2%) were undocumented. Undocumented cases had lower admission creatinine (2.1 vs 2.9 mg/dL;
